AngularJS(10)-数据验证

AngularJS 表单和控件可以提供验证功能,并对用户输入的非法数据进行警告。客户端的验证不能确保用户输入数据的安全,所以服务端的数据验证也是必须的。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>数据验证</title>
    <script src="angular-1.4.1/angular.min.js"></script>
</head>
<body>

<h2>数据验证</h2>

<form  ng-app="myApp"  ng-controller="validateCtrl"
       name="myForm" novalidate>

    <p>用户名:<br>
        <input type="text" name="user" ng-model="user" required>
  <span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
  <span ng-show="myForm.user.$error.required">用户名是必须的。</span>
  </span>
    </p>

    <p>邮箱:<br>
        <input type="email" name="email" ng-model="email" required>
  <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
  <span ng-show="myForm.email.$error.required">邮箱是必须的。</span>
  <span ng-show="myForm.email.$error.email">非法的邮箱。</span>
  </span>
    </p>

    <p>
        <input type="submit"
               ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||
  myForm.email.$dirty && myForm.email.$invalid">
    </p>

</form>

<script>
    var app = angular.module('myApp', []);
    app.controller('validateCtrl', function($scope) {
        $scope.user = 'John Doe';
        $scope.email = 'john.doe@gmail.com';
    });
</script>

</body>
</html>
